The greater the level of physical training,the higher the proportion of energy derived from the oxidation of ____ during exercise below VO_2max. A)glucose B)protein C)amino acids D)fatty acids

Question

Quizplus · Accepted Answer

As the level of physical training increases, the body becomes more efficient at using fatty acids as a fuel source during exercise below the maximal oxygen uptake (VO_2max). This is because the body learns to spare glycogen stores and rely more on fat metabolism, which is a more sustainable energy source for long-duration exercise. Therefore, the proportion of energy derived from the oxidation of fatty acids increases as physical training level increases.

The Greater the Level of Physical Training,the Higher the Proportion
